    Abstract : Shikimic acid production using recombinant E.coli has been developed during the past 15 years due to the increased demand of this product, primarily as a starting material for the anti-influensa medicine Tamiflu?. A detailed metabolic analysis of a shikimic acid producing E. READ MORE

  2. 2. Glycolytic flux regulation in Saccharomyces cerevisiae during anaerobic growth and starvation

    Author : Elisabeth Thomsson; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Saccharomyces; Yeast; Starvation; Energetics; Chemostat; Anaerobic;

    Abstract : The physiology of S. cerevisiae under anaerobic growth conditions is of interest not least during implementation and development of industrial yeast-catalysed ethanol fermentations in order to maintain a productive yeast population. READ MORE

  3. 3. A holistic view on transcriptional regulatory networks in S. cerevisiae: Implications and utilization

    Author : David Bergenholm; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; S. cerevisiae; transcriptomics; chemostat; Transcription factors; regulatory networks;

    Abstract : Life; perhaps it is bold to start an abstract with this powerful word, but this is where I will start. My research is at the heart of life. READ MORE

  4. 4. Physiological Engineering of Xylose Utilisation by Recombinant Saccharomyces cerevisiae

    Author : Nina Quednau Meinander; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein burden; physiology; fed-batch fermentation; chemostat; recombinant Saccharomyces cerevisiae; ethanol; xylose; xylitol; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Xylitol production by recombinant, XYL1-expressing Saccharomyces cerevisiae was investigated in fed-batch fermentation using different cosubstrates for growth, and generation of reduced cofactors and maintenance energy. Xylose was converted into xylitol with 1:1 yield. READ MORE

  5. 5. Fermentation Inhibitors in the Production of Bio-ethanol: Detoxification of Lignocellulose Hydrolyzates and Physiological Effects of Furfural on Yeast

    Author : Ilona Sárvári Horváth; Chalmers University of Technology; []
    Keywords : detoxification; fermentation inhibitors; metabolic flux analysis; Saccharomyces cerevisiae; lignocellulose; ethanol; chemostat; furfural conversion;

    Abstract : Different strategies to overcome inhibitor problems in the production of bio-ethanol from lignocellulose hydrolyzates with the yeast Saccharomyces cerevisiae were examined. The strategies included detoxification prior to fermentation and in situ detoxification of furfural. A strain development for improved inhibitor tolerance was also initiated. READ MORE
